    Merging alignments in mosaik - problems

    Hi! I'm having trouble merging alignments in colour space (SOLiD) and base space (454) in Mosaik (version 1.0.1388). This is what I have done:

    Code:
    ################
    ## 1. Build Mosaik binary files from SOLiD reads, 454 reads and  consensus
    
    # Build binary from consensus
    >MosaikBuild -fr scaffolds.fna -oa scaffolds.dat
    
    # Create jump database for consensus
    >MosaikJump -ia scaffolds.dat -out saffolds_15.dat -hs 15
    
    # Build binary from consensus in colour space
    >MosaikBuild -fr scaffolds.fna -cs -oa scaffolds_cs.dat
    
    # Build binaries from 454 reads
    >MosaikBuild -fr 1.TCA.454Reads.fna -fq 1.TCA.454Reads.qual -out 454reads.dat -st 454
    
    # Build binary from SOLiD reads
    >MosaikBuild -fr solid.csfasta -fq solid.qual -out solidreads.dat -st solid
    
    
    ################
    ## 2. Map 454 reads to consensus
    >MosaikAligner -in 454reads.dat  -out 454reads_aligned.dat -ia scaffolds.dat -hs 15 -mmp 0.05 -mhp 100 -act 55  -p 2 -j scaffolds_15.dat -bw 51
    
    # then sort
    >MosaikSort -in 454reads_aligned.dat  -out 454reads_sorted.dat
    
    
    ################
    ## 3. Map SOLiD reads to consensus
    >MosaikAligner -in solid_reads.dat  -out solid_reads_aligned.dat -ibs scaffolds.dat -ia scaffolds_cs.dat -hs 15 -mm 4 -mhp 100 -act 25  -p 2
    
    # then sort
    >MosaikSort -in solid_reads_aligned.dat  -out solid_reads_sorted.dat 
    
    
    ################
    ## 4. Merge alignments from 2. and 3.
    >MosaikMerge -in 454reads_sorted.dat -in solid_reads_sorted.dat -out all_reads_sorted.dat


    The last step is where I run into problems. I get "ERROR: Found an inconsistency in the reference sequences. Merged alignment archives must share the same subset of reference sequences."

    Any advice? Is there a bug somewhere or am I just doing something wrong?

    Multiomic Liquid Biopsy: What DNA/RNA Panels Reveal That DNA Alone Can’t
    by SEQadmin2



    Tumors contain complex mixtures of cell populations that evolve in response to treatment and host-specific factors. Tissue biopsies provide only static snapshots of a tumor’s state. But what if we could follow that evolution over time using a minimally invasive technique?

    Liquid biopsies can detect tumor-derived material circulating in the bloodstream, providing a way to study treatment response, detect emerging resistance, and discover new biomarkers. Circulating

    New Genomics Technologies Take Aim at Long-Standing Limits
    by SEQadmin2


    Researchers using sequencing and genomics tools often have to make trade-offs. They can choose between speed or scale, short reads or long-range information, or targeted panels or a view of the whole transcriptome. New technologies that have been released this year are built to address those tough choices.

    We asked six companies the same four questions to learn about their latest products. The new technologies bring a lot to the table, including rethinking sequencing
